DEIEECATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 763,084,- dated June 21, 1904.

I Application filed April 5, 1904. Serial No. 201,675. (No model.)

To all whom it may concern:

Be it known that we, MARTIN ALToLAeUIRRn and JOAQUIN ZUBILLAe ,citizens of the United States, residing at Ingenio El Pilar, Artemisa, Cuba, have invented new and useful Improvements in Defecating Apparatus, of which the following is a specification.

Our invention pertains to defecating, and has for one its objects to provide a defecating apparatus which is simple, inexpensive; and sturdy in construction and yet continuous in operation and possessed of high capacity.

Another object of the invention is the provision, in a defecating apparatus, of means whereby scum may be expeditiously removed from thejuice without interruption of the defecating operation.

Another object is the provision of a-defecating apparatus constructed with a View of causing the collection of scum at a particular point, this with a view of facilitating the re-- moval ,of the scum from the juice.

With the foregoing in mind the invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which Figure l is a longitudinal vertical section of the apparatus constituting the preferred embodiment of our invention; Fig. 2, a front elevation of the apparatus, with parts broken; Fig. 3, a detail transverse section, on an enlarged scale, taken in the plane indicated by the line 3 3 of Fig. 1; Fig. 4:, an enlarged broken transverse section taken in the plane indicated by the line 4 4 of Fig. 1, and Fig, 5 a broken perspective view of the plate for separating the juice and the scum precedent to the discharge of thelatter from the apparatus.

Similar letters designate correspondingv parts in all of the views of the drawings, referring to which A is the casing of the apparatus. This casfrom the sameend of the portion a and open at its upper end. 7

B is a head fixed in the lower end ofthe leg 0 of the casing; C, a head fixed in the end of the casing portion oremote from the logo,- D ,1), tubes, preferably of copper, fixed at their ends in the heads B C and disposed in the portion a and the leg 0 of the casing; E,

casing portion a, leg 0, and frame (land is.

provided with an opening f, a spout 9, disposed below said opening, and a conduit h, arranged to receive from' the spout and having for its purpose to convey scum to any desired point. In virtue of the said wall G being hinged asdescribed it isadapted to be readily opened, so as to afford access to the tubes D and the interior of the casing A for the purpose of repairing or cleaning the apparatus. I

H is a valved pipe connected with the lower portion of the casing-leg c and adapted to supply the same with cold juice or saccharine solution; I, a pipe leading from the end of the portion a remote from the leg 0 and having. agooseneck disposed in about the lIOlIZOIltfiI plane shown 1n Fig. 1; J, a valved pipe cor n In the practical operation of the apparatus the valve in the pipe H is opened and cold juice or saccharine solution is permitted to flow into the casing A until it reaches the level indicated by the'dotted line i in Fig. 1.

With this done the valve in said pipe is closed and live and exhaust steam is let into the chambers F and B, respectively, until the juice in the casing is brought to aheat of 100 Centigrade. The valve in the pipe I is then opened and the discharge of the clarified juice through the said pipe I then takes place. This operation is continued indefinitely and at intervals of about thirty minutes. Scum is removed from the juice in the frame (Z by means presently described.

In virtue of live or superheated steam being supplied to one end of the casing A and exhaust or low-pressure steam to the other end thereof there is a marked difference of temperature in the ends or extremes of the apparatus which produces circulation of the saccharine solutionin the casing. Such difference of temperature also gives rise to the circulation of air in the casing, and the inclined upper wall of the casing portion a facilitates the escape of air and guides the current of "solution toward the frame (Z, with the result that the accumulation of scum in said frame (Z is materially accelerated.

L L, Fig. 3, are angle-irons fixed to the side walls of the frame (Z in about the same horizontal plane as the opening f in wall G. M is a plate movable on said angle-irons and in a housing 3', connected to and extending rearwardly from the rear Wall of the frame (Z; N, a rod connected to the plate M and extending through a stufling-box is at the rear end of the housing j; P, a follower disposed in the frame (Z above the horizontal plane of the plate M, and Q a handle-rod connected to said follower and extending rearwardly through a stuffing-box Z on the rear wall of the frame cZ.

When during the continuous operation of the apparatus scum accumulates in the frame (Z to a height of, say, twelve inches, the plate M is moved, through the medium of the'handle-rod N, in .the direction of the arrow in Fig. 1 until its forward end brings up against the forward end wall of the frame cZthis to separate the comparatively dry scum from the clear juice or saccharine solution. With this done, the follower P is moved from its normal position at the inner side of the rear wall of frame (Z forwardly, or in the direction of the arrow, and the scum is moved before said follower and discharged, through the opening f in wall G, into the conduit or launder h. The opening f in wall G is normally closed by a gravitating gate f, which opens under the pressure of the south and after the discharge of the latter resumes its normal position. The scum may be conveyed to any desired point and disposed of in any suitable way. \Ve prefer, however, to mix the scum with equal volumes of water and to boil and decant the mixture, since the same has approximately 1.5 to 2 Baum and is excellent for saturation between mills.

The defecating operation is not interrupted or otherwise affected by the removal of the scum in the manner described, and all the attendant has to do in order to reestablish the accumulation of scum in the frame (Z is to return the plate M and the follower P to their normal positions, so as to render the frame (Z entirely open to the interior of the casing.

Because of the casing A having the horizontal portion a, the upper wall of which is inclined, and a leg 0, depending from one end of said portion a, it will be observed that the ascending currents will meet at right angles to each other at a point below the frame (Z, and in consequence the portion of the juice adjacent to said frame will be kept highly heated. This is an important advantage, since it is essential to the proper separation of scum from the clear juice that the solution be kept constantly at or about 100 centigrade when adjacent to the frame d.

We prefer in practice to connect the discharge-pipe I to the lower portion of the casing portion a and to make said pipe of about the same diameter as or slightly larger than the pipe Notwithstanding the advantages of our novel apparatus as pointed out in the foregoing it will be observed that the apparatus is simple, compact, and sturdy in construction and embodies no delicate parts, such as are likely to be affected by the high heat and get out of order after a short period of use.

We have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of our invention in order to impart a full,.clear, and exact understanding of the same. We do not desire, however, to be understood as confining ourselves to such specific construction and relative arrangement of parts, as such-changes or modifications may be made in practice as'fairly fall within the scope of our invention as claimed.
